To all whom it may Concern:

Be it known that I, ELISA M. Souvrnnnn, a citizen ofthe United States, and resident of Jacksonville, county of Duval, State of Florida, have invented certain new and useful Improvements in Windmills7 of which the following is a specification.

This invention relates to motors operated scription taken in connection with the drawings.

In the drawings,

Figure l is a perspective view vof a construction embodying my invention;

Fig. 2 is a view of the impeller separate from the support blades;

Fig. 3 is aV sectional view showing a slightly modified way of making the vanes.

As shown in the drawings, my device is mounted in a frame having the four posts 1 connected by cross pieces 2, 3, 4 and 5 at the top, together with suitable bracing members. Below the top there is a secondary frame made up of the connecting members 6, 7 8 and 9 with suitable cross braces for strengthening the frame. At the top there is a cross piece 10, which as hereafter explained carries the bearing for the upper end of the rotary member of my device and below that member there is a cross piece 11 which carries the lower bearing. It will be understcod that my invention is not limited to the use of this particular form of frame for supporting the rotary motor and that any other suitable form of support may be used.

The main element of my invention resides in the rotary impeller which. as shown in Fig. 1, is provided with a shaft 12 at. the top and a bearing 13 at the bottom. Radiating from the axis in line with the bearing 13 and shaft 12 are the vanes or blades 14, 15, 16 and 17. These blades or vanes are preferably made of sheet metal and are curved in cross section so as to be turned by the wind. The two opposite blades 14 and 16 are cut away at the center providing openings 18 and 19 which permit the passage of air i spe-aannamtenement. V Patented Nov. 1s, 1er.v

through them. The vanes-furthermore, are` substantially V- shaped in form with the top of the V at'the axis, whereby they have a'n upper edge extending downward'at an angle to a pointed outer` margin. The Vmateralof the vane is bent over at the top to form aiapge 20'wh'ich extends at an angle up to a point near the axis. The purpose of this flange 1s to catch the air striking the vane lso that there will be an upward pressure against the under side of this fiange tending to raise the rotary member as a whole, thus relieving the weight on the bearings. anges 2O are formed preferably byv cutting the sheet metal material of the vane and bending the parts so as to make overlapping sections. This is necessary owing to the curvature of the blades.

Below the vanes 14, 15, 16 and 17 I place a heavy ring 21, this ring being substantially below the outer points of the vanes. It is connected to the shaft at the axis of the rotary member at thebottom by any suitable means, such as the rods 22. It is also connected to the outer pointed ends of the vanes by means of the tension wires 23 which extend at an angle from the end of the vane to the Weighted wheel constituting the fly wheel. These tension wires serve to trans- These mit the power applied to the vanes by the In some instances the shaft on -which the l vanes are mounted may be made to extend entirely from the top to the bottom and in that case I preferably make one of the vanes of two sheets of metal fitting against the opposite sides of the shaft, as shown in Fig. 3, where 24 represents the shaft and 25, 26 represent the two sections making up the two opposite vanes.

It will be observed that the construction above indicated will not only eectively utilize the force of the wind kreducing the friction very much butthat it may be made easily and without much expense.

Having described the invention what is claimed and desired to be secured by Letters-Patent is, v

1. The combination in a wind motor of lradiating sheet metal vanes curved in horizontal section and having upper edges inclined downward from the axis, the upper inclined edges being cross cut and bent over in overlapping sections to form a flange along the top, a heavy ring below said vanes concenwhich are curved in cross section and each having upper inclined edges being cross cut and bent over inbverlapping sections tol form a flange along the top, a heavy ring below said vanes concentric with the :uns of rotation and inclined Connections from the ends of said vanes to said rinO.

3. A Wind motor comprising rotatable ra- 15 Vdiatiing-shaped vanes, the top of the V in each `case'being at the axis of rotation and theedge of each vane being bent to form a flange along the top and each vane being curved in horizontal section.l a heavy ring 20 below said vanes and rotatable therewith,

and connecting means extending from the outer ends or said varies to said ring at an angle on the side from which the liange pro-V ]ects.

In testnnong.7 whereof I affix my signa-ture.
